In this paper published in Diabetes Care, the authors mapped a meta-analysis from 1990 to 2010 and found that in 2010 27% of blind people and 64% of visually impaired people had DR to blame for their sight problems. The highest DR-related blindness and visual impairment numbers were in sub-Saharan Africa and South Asia.
